nU'roMonInn rEDAL-LOCKING WEDGn 1 Application led lNovmber This invention relates to 4work holders 4for assembling purposes, and the improvements particularly embody an automobile pedal looking wedge.

`rl`he primary object of the invention has Ibeen to devise `a channel-'like hollow wedg- 'ing unit, which'is of .effective and durable although Alight-weight construction, which may be rapidlyandleconomically ymanufactured, and Awhich `is 'so formed that-,of itself or fwithout .auxiliary Amovable parts, it is adapted for the iplural `or conijoint tem- -porary locking, in centralized positions, of all of 'the "transmission band controlling pedals and their mounting shafts,`ssociated with the transmission assembly of certain 'types offautomobile engines, such as the wellknown lFord transmission, `for insuring the proper registration of parts and thereby `greatly facilitating theV :otherwise "troublesome/replacing ofthe relatively heavy transmission cover assembly, `whe'nsaid'cover assembly `has been removed,;as it is necessary to do, forthe relining of the transmission fbands'or for other purposes.

AAlthough the .l present Iinventionk relates only to pedal locking means itself, uniquely formed las a channel-like Ahollow `integral wedging unit, l:in order Lto fmore readily understand its `special utility, it fmay not "be amiss to briefly-state that 'the transmission bands, which encircle A:theirrespectivedrums, `terminate in fperipherally :projected `spaced lugs. Theseilugs are formed withend-opening slots, for the seating `of their lrespee- `tive pedal operated shafts, and 'the said Ishafts are "encompassed by Coil springseX- `tending between said flugs, the whole functioning 'in 4a manner Well understood, and 'the said p'edalsyshafts: andreoil springs forming a part of the transmission `cover assembly. e

Also, it may not be f amiss to 'further .state that, in the actual luse rof @my inventionpallthough 'functioning independently, -I preferably employ my pedal lockingfwedge-inlconjunction with certain other worlrholders, including a tool for holding all of said vcoil springs `conjoint-lyfeom'p'ressed and a clamping' device for holding said slotted lugs conjontly in proper upright position, frequently heretofore done by a binding cord around the same, but these separate devices are not herein illustrated, as they do not form a part of the present invention itself, although y1,1924. iSeril No. 747,362.

they `may be marketed and used therewith .as partsof a lwork holding assembling set.

It follows, therefore, that `with said lugs held rproperly aligned, and with said -`coil springs held compressed,fthen with my pedal ,loclnngvvedge applied-in position, as herein after. disclosed, all of these lannoyingly eas- ,ilydisplacedparts are, in respective groups, .held intimately locked in `proper alignment, when the transmissioncover assembly, asa vvliole,ean facilely be replaced without any trouble and with much savingof time, as no obstruction is ofl'ered by unalig'ned parts.

With these prefacingremarks, ,generally outlining the object, nature-and functioning of mypresent invention, reference willnow be immediately had to the accompanying drawings, illustrating a practicallenibodi ment of the improved device and Vits manner of application, in which drawings `Figure 1 isan outside ,perspective view flooking towards the apex -end of the pedal locking wedge; Figure'Q isa transverse sectional view thereof asiapplied in its opera'- tive position, *the ypedal arms being also shown Ain cross-section; and VFigure 3 rear perspective view of the transmission cover section and pedal assembly', with the pedal locking wedge illustrated in itsloperavis a Q tw position and the Whole being readyfdr a5 bodily replacing operations,exceptinglthat i the sloping door or'top c` 1osure,wliihisiil- Alustrated in the vi`eiv,lwol`ld not in fact-"have the bearing supports I6, Z0 and 9A, respectively journaling the clutch iI'Jedalf'sh'aft :15, the reverse pedal .shaft vand 'the transmission brakepedal shaft'. The clutoh pedal is indicated at 12, its arm at 13 'and 'the Alatters shaft-clamping collar at 14, and corresponding elements of the reverse pedal assembly and the transmission brake pedal assembly are respectively indicated by the 'numerals 17-18-19 and 21-22-23.

The pedal locking wedge itself, being` preferably of pressed steel construction, is formed from a properly cut blank of the met-al, which blank is so finally s haped, by die-pressure, as to embody a main cross-wall or cross-web 25 that terminates longitudinally in tapering marginal flanges or wedgeshaped side-walls or side-webs 2G and 27, the tapering or beveled edge faces of which are respectively indicated at 28 and 29, and the said cross-web 25 having a central longi-- tudinal slot 30 that opens through the apex end of the device, providing as it were a bifurcate or forked channel-body wedge.

At the base end of the device, the crossweb 25 is preferably formed with a forwardly projected or out-turned flange strip 3l, in the nature of a laterally disposed elongated lip, which may be slightly curved inwardly, or of arcuate transverse section, to provide for a withdrawing handle or linger grip, under which the forefinger of the operator may conveniently be disposed.

The base end of the device is wholly open, as at 32, and also the space between all of the webs 25-26-27 is wholly open or unobstructed, whereby proper clearance space is provided for the lower angularly disposed portion of thereverse pedal arm 18.

At the apex end of the device, although perhaps not at all strictly essential, inturned transverse webs or flanges may be formed,

which are readily provided for by appropriate corner slits 3A, and these are preferably employed as they afford both reinforcing 0r trussing means, for the forked or separated sections, and sn'iooth-linished end-facing webs.

It will be seen from Figures 2 and 3 that, in applying my improved device in locking association with the pedal assembly, the slot 30 straddles the shaft l5 with the forward face of the web 25 in engagement with Vthe inner end face of the clutch pedals clamping collar lll, and with eac-h of the tapering or beveled edge faces 28 and 29, of the sidewebs 26 and 27, in direct wedging engagement with the respective inner end faces of the clamping collars 19 and Q3 of the reverse pedal and the transmission brake pedal. It is further to be noted that in applying and detaching the locking wedge it is not necessary to adjust any auxiliary movable parts, but in applying the same the onlj7 one necessary operation is to force the hollow wedge down home, it being also observed that this may readily be done, owing to the unobstructed base end opening 82, and the space between the main cross-web 25 and the side webs 26 and 27, providing for the proper clearance to allow the hollow channel-lilre wedge to encompass the angularly disposed lower portion of the reverse pedal arm 1S.

Thus there is provided therebetween a wedging interlock, as it were, and the several pedals may be properly centered and conjointly maintained firmly locked, as grouped assemblies, with this simple unitary device, in such desired centered position, for the facile replacement of the transmission cover as hereinbefore outlined.

lVhat l claim, as new and patentable, is

l. A unitary pedal locking wedge, for the conjoint temporary holding of automobile pedal assemblies, embodying a main cross-web that terminates at its sides in longitudinally tapering rearwardly projected wedge-shaped side-webs, providing for a substantially unobstructed space therebetween, the said cross-web being provided with an elongated longitudinally disposed slot opening out through the apex end of the device.

A unitary pedal locking wedge, for the conjoint temporary holding of automobile pedal assemblies, embodying a main croi-'s web that terminates at its sides in longitudinally tapering rearwardly projected wedgeshaped side-webs, providing for a substantially unobstructed space therebetween, and that terminates at its base end in a forwardly projected transverse flange strip, the said cross-web being provided with an elongated longitudinally disposed slot opening out through the apex end of the device.

3. A unitary pedal locking device, for the conjoint temporary holding of automobile pedal assemblies, comprising a pressed-steel channel-like hollow wedge, having an unobstructed open base, embodying a main crossweb that terminates at its sides in longitudinally tapering rearwardly projected wedgeshaped side-webs, also terminating at its base end in a forwardly projected transverse flange strip, and terminating at its apex end in rearwardly projected apex-webs extending approximately from the apex ends of said side-webs towards the center of said cross-web, the said cross-web being provided with an elongated longitudinally disposed slot, opening out through the apex end of said device terminally of the inner ends of said apex-webs.

In testimony whereof, l affix my signature.
